PROBLEM TO BE SOLVED: To give a sense of reliability to consumers or the like and to prevent a lowering of heat transfer efficiency. SOLUTION: This triple-bottom structure for a cooking container has a body 20 for holding food, a stiffening plate 30 disposed extending from a bottom wall of the body 20 to the edge part of a sidewall and formed with a large number of holes 32, and a heat transfer plate 40 disposed between the body 20 and the stiffening plate 30 to transfer external heat into the body 20. The heat transfer plate 40 is pressure-fitted and bonded to the body 20 and enters each hole 32. Since the heat transfer plate 40 is pressure-fitted and bonded to the body 20 and enters each hole 32, whether the heat transfer plate 40 is disposed at the bottom wall is easily confirmed with the naked eye in a manufacturing process. The occurrence of defectives can thereby be prevented, and a sense of reliability can be given to the consumers or the like. COPYRIGHT: (C)2005,JPO&NCIPI
